In court documents, police say that video surveillance at the Escape Outdoors store in the Westfield Southcenter mall shows Saunders shooting the two boys as they attacked his younger brother and a friend.

Speaking following his client’s arrest, Saunders’ attorney claimed Saunders was shopping elsewhere in the mall when he got a call for help from his teenage brother. His brother told him that Jones, the injured teen and two other boys were taunting him and a friend and making threatening comments to the friend, a teen who’d been shot weeks before.

After the shooting, Tukwila detectives learned that Saunders might have headed to Oregon and notified authorities there. Portland police arrested Saunders while investigating an unrelated disturbance.

The shooting capped a violent weekend during which 11 people were shot in the greater Seattle area. Police said at the time that many of the shootings, including the violence at the mall, stemmed from rivalries between street gangs.

Jones and the injured teen had ties to a South Seattle street gang, according to court papers. Authorities have claimed Saunders had ties to a Central District gang, though his attorney disputed those assertions.
